It would "terminally deprecate" the <tt>jdk.scripting.nashorn</tt> module implementing the Nashorn JavaScript scripting engine (the <tt>jdk.nashorn.api.scripting</tt> and <tt>jdk.nashorn.api.tree</tt> packages). Removal of the implementation would fall into a later release of Java.</p> <p style="margin: 10px 0 0 0">It looks like this JEP will be targeted at Java 11 unless some community group comes forward to guarantee maintenance of Nashorn within the JDK for the long term. I've seen no takers for that.</p> <p style="margin: 10px 0 0 0">Nashorn was introduced to Java 8 as a replacement for the Rhino engine provided by Java 6 and 7. JEP 335 does not include a proposed replacement implementation, which would mean that as of Java 12 or Java 13 we might be in a position where <em>no</em> JavaScript engine was part of the standard Java runtime. Some alternatives have been proposed (Project Detroit? Graal?) but they don't seem to be ready yet. I don't know which way to bet as to whether the removal of Nashorn will be delayed until a viable alternative (even a separated version of Nashorn) is available outside the Java runtime: the main impetus here is that Oracle don't want to spend time supporting it.</p> <p style="margin: 10px 0 0 0">It doesn't look as if we call any of the Nashorn APIs directly. We do have Nashorn-dependent tests in the IdP because our tests for scripted matchers include separate scripts that work under Rhino and Nashorn. The main issue with this would therefore be that <em>deployers</em> of the IdP (and potentially the MDA, which also allows for scripting) would find that their code would no longer work.</p> </td>
